See, see! Just like a hand, right? Don't lie, you agree. Sure, it's not a good omnipurpose gripper, but I see why you like these so much. No, no, 'shake' my 'hand' like you solids do- [here, the unmistakable burbling noise of a goo giggling] - it'll be fun, I have a surprise!!
HA! Cool, isn't it? I call it a 'hand buzzer'!
